![]() Marker-based approaches have the advantage of providing a solution for both tracking and registration in one go. This principle is used by many commercial tracking and motion capturing solutions, such as OptiTrack (Natural Point, Inc., Corvallis, Oregon, USA) or Vicon (Vicon Motion Systems Ltd, UK), which operate in an outside-in fashion. The tracking of retro-reflective spheres with infrared (IR) cameras has been shown to be a more robust alternative. However, such approaches are sensitive to uneven, non-controllable lighting conditions. A fast and cheap method is to track known image patterns ( fiducials) with standard red-green-blue (RGB) visible light cameras. ![]() Optical registration and tracking can be accomplished with marker-based approaches, which rely on artificial indicators rigidly attached to real world objects.
